Chromatica is the sixth studio album by American singer Lady Gaga. It was released on May 29, 2020, by Streamline and Interscope Records. Originally scheduled for April 10, 2020, the album's release was delayed for seven weeks, due to the COVID-19 pandemic. Gaga and BloodPop served as the album's executive producers. Chromatica is a dance-pop, synth-pop and electropop project with elements of house, disco and other electronic genres. The album is named after an imaginary, dystopian planet, which the singer described as a place where "equality rules". The album covers themes of mental health, trauma, self-worth, finding love through hardship, which contrasts its positive and uptempo production. It features guest vocals from Blackpink, Ariana Grande and Elton John.
Three singles were released to support the album. The lead single, "Stupid Love", was released on February 28, 2020, and peaked inside the top-ten in over fifteen territories, reaching number five in the United Kingdom and United States. Its follow-up, "Rain on Me" with Ariana Grande, arrived on May 22, 2020, and debuted atop the charts in the UK and the US. "Sour Candy" was released as a promotional single a day ahead of the album's launch, followed by a remix version of "Free Woman" at a later date. "911" was released as the third single on September 25, 2020.
Upon release, Chromatica received generally positive reviews from music critics. It debuted atop the Billboard 200 chart with 274,000 album-equivalent units, marking Gaga's sixth consecutive number-one album in the US. The album also topped the charts in several other countries, including Australia, France, Mexico, Ireland, Canada, Portugal, Italy, Netherlands, Scotland and the UK. It became the fastest selling album of the year in the UK, as well as the year's fastest selling vinyl record.
